What exactly does pointing the transducer straight down do?
I have always followed this:
"Transducer Installation-the most common problems with sonar performance.
When I talk to fishermen who are having trouble getting a good
reading with their sonar unit, particularly at high speed, the most
common problem is a poor transducer installation. Nothing can affect
your sonar's performance as much as a poorly installed/placed
transducer. It must be level with the transom and mounted in a smooth
water flow area, 1/8 inch below the bottom of the hull. The bottom
surface of the transducer needs to be parallel to the waterline, not
in line with the bottom of the hull."
And because I go backwards, I have it pointing out in front. But I mounted mine to the strap with PVC so I can tilt it up. The cutting board was for flexibility.
